Ancor Dark Blue 18 AWG Tinned Copper Wire - 35'

Ancor Dark Blue 18 AWG Tinned Copper Wire in a 35-foot spool is a marine-grade electrical conductor engineered for saltwater environments where standard wiring fails. Built to exceed UL 1426, ABYC, and US Coast Guard Charter Boat (CFR Title 46) standards, this tinned copper wire is the electrical backbone of reliable boat systems—from bilge pumps and navigation lights to radio installations and auxiliary charging circuits.

The 18 AWG gauge is sized for moderate-current applications on small to mid-size vessels, offering the right balance between current-carrying capacity and wire flexibility. Premium vinyl insulation is rated at 600V and handles temperature extremes from −40°F to +105°C dry and +75°C wet—critical for deck wiring, through-hulls, and bilge installations exposed to temperature swings. The insulation resists salt water corrosion, battery acid, gasoline, oil, abrasion, and UV radiation, ensuring longevity in the harshest marine conditions where standard copper wire oxidizes within months.

This wire suits weekend fishermen upgrading basic trolling motor circuits, anglers rewiring aging boats, and serious offshore operators building or restoring electrical systems that must survive salt spray and constant vibration. The 35-foot length accommodates single circuits or multiple shorter runs, and the tinned copper construction—unlike bare copper—won't corrode even when salt spray makes contact. For boat owners tired of replacing corroded wiring every few seasons, marine-grade wire is not a premium choice but a necessity.
